Abstract
The invention discloses a method and a system for information interaction in an uplink coordination set. The method comprises the following steps that: in an uplink coordination process, all cells in a coordination set of coordination user equipment (UE) perform checking result interaction; and each coordination cell in the coordination set makes a decision about whether the coordination cell is required to transmit data to a serving cell or not in a distributed negotiation way when learning that the serving cell has an unpacking failure according to checking results of all the cells interacting with the coordination cell, and makes a decision about whether the data are required to be transmitted totally or partially if the coordination cell is required to transmit the data to the serving cell. The transmission of transmit blocks (TB) or only a part of code blocks (CB) is selected according to needs, and a part which is most required by the serving cell is transmitted under the condition of lowest overhead, so that the pressure of an X2 interface/air interface is reduced, and data transmission efficiency is improved.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to the mutual method and system of a kind of uplink coordinated concentrated message.
Background technology
IMT-Advanced (International Mobile Telecommunications-Advanced; Senior international mobile communication) research of key technology from 20 the end of the century 3G (3rd Generation; 3G (Third Generation) Moblie) just having begun in technology standardization is accomplished, is the main developing direction that information technology has been represented in NGBW communication.IMT-advanced compares with existing systems; With realizing higher data transfer rate and bigger power system capacity; Target peak speed is: low speed moves, under the focus covering scene more than the 1Gbit/s (gigabit/second), 100Mbit/s under high-speed mobile, the wide area covering scene (100,000,000/second).
Multipoint cooperative transmission technology (Coordinated Multipoint transmission/reception abbreviates CoMP as) is one of key technology of LTE-Advanced (Long Term Evolution-Advanced, advanced long-term evolution system).CoMP is primarily aimed at the UE (UserEquipment in cell edge area; Subscriber equipment) receive the disturbed condition serious situation, carried out the multiple spot data transmission to disturbing UE by a plurality of cell cooperatives, or coordination, scheduling through a plurality of minizones; To reach the elimination presence of intercell interference; Improve signal quality, improve user and system data throughput, and then improve the purpose of system spectrum utilance.
The CoMP The Application of Technology can be divided into two kinds of intra-eNB CoMP and inter-eNB CoMP according to the difference of networking mode.Intra-eNB CoMP is meant that the cell/section of participating in cooperation belongs to same base stations control, and characteristics are that communication is accomplished at an inside of base station between cooperation cell, the transmission that need not pass through X2 interface or eat dishes without rice or wine; Inter-eNB CoMP is meant that the cell/section of participation cooperation belongs to a plurality of base stations control, and characteristics are that informational needs perhaps eats dishes without rice or wine to transmit through X2 interface when communicating by letter between cooperation cell.Therefore, it is fast that the application of intra-eNB CoMP has speed, the characteristics easily of cooperating, and inter-eNB CoMP more has flexibility in the selection of cooperation collection, thereby have application scenarios widely.
Because in traditional agreement, the interface between the base station, for example X2 interface or other are eated dishes without rice or wine, and only transmit low volume data, so the application meeting of inter-eNB CoMP brings sizable pressure to X2 interface, even because interface capability restriction collaborative effect.Therefore necessary to the optimization of the mutual data of X2 oral sex.
The CoMP technology is divided into two kinds of up CoMP and descending CoMP by link direction.Descending CoMP is meant that a plurality of cooperation cell unite for the user sends data, unites the data that receive UE and up CoMP is meant a plurality of cooperation cell.
Descending CoMP technology mainly is divided into following two types in the standard at present: Combined Treatment (Jointprocessing; Abbreviate JP as): in the sub-district that each cooperation is concentrated, all send identical data, the improving gain reception of user's similar grand branch collection capable of using to the user; Cooperative scheduling/wave beam forming (Coordinated Scheduling/Coordinated Beamforming; Abbreviate CS/CB as): the user that the sub-district that each cooperation is concentrated is merely in the own sub-district sends data; And utilize the beam shaping technology to make signal to this community user strong the time; A little less than user on the same resource of neighbor cell disturbed, improve reception with the mode that improves signal to noise ratio.
And up CoMP mainly adopts Combined Treatment between the cooperation cell, is about to UE upstream data that multiple spot receives and merges processing and receive accuracy to improve.The Combined Treatment upstream data requires interaction data between the cooperation cell, be divided into the opportunity of interaction data cooperation cell to the UE data parsing before with resolve back two kinds.The resolution data process can be brought extra processing burden to cooperation cell; But the data after resolving diminish with respect to the data volume before resolving; Therefore can alleviate the pressure of interface between the base station to a certain extent; And Serving cell do not separate to and cooperation cell is separated under the right situation, can be fast make the affirmative acknowledgement response to UE.
The up Combined Treatment scheme of discussing at present generally all is the result after mutual the parsing; Sub-district in promptly each cooperation collects is independent earlier resolves; And mutual final analysis result (promptly whether separating) to TB; If it is right that Serving cell is not separated, separate right cooperation cell and can send and separate right TB (Transmit Block, transmission block) and give Serving cell.
Motion R1-093797 proposes, mutual ACK (ACKnowledge, affirmative acknowledgement)/NAK (Non-ACKnowledge, negative response) between all eNB (enhanced Node B, improved base station), refinement the processing mode under the various situation.All do not separate under the right situation in all base stations, mutual soft bit information, or IQ sampled data (IQ samples) also can improve accuracy after merging.
Motion R1-09-3019 proposes to increase the mutual of CB (code block, code block) level, soft bit levels.To IQ sample information (IQ samples), expense increases successively from TB, CB, soft bit information, and the pressure that X2 interface is perhaps eated dishes without rice or wine also increases successively.This motion mainly proposes cooperation cell and selects only other packet of level to send to Serving cell according to the ability of X2 interface, and Serving cell merges according to the rank of the packet of all cooperation cell of receiving successively, and resolves.
But, in the above-mentioned motion, only mention the mutual of TB level, CB level; But stagger the time if Serving cell is separated, cooperation cell is sent TB level or the whole data of CB level, and then the expense when information interaction is bigger; Pressure to X2 interface/eat dishes without rice or wine is also bigger, and data transmission efficiency is not high.And mutual soft bit information and IQ data, the processing burden of Serving cell is heavier.

Embodiment
Main purpose of the present invention is; To the characteristics of interaction data between the base station among the up CoMP, propose a kind ofly to concentrate the method for interactive information in cooperation, existing interactive mode is improved; Make that the data volume of interface reduces between base station or the sub-district, the content of transmission is more effective to cooperation.
For realizing above-mentioned purpose, design of the present invention roughly is described below:
Process research through data among the LTE are sent can learn that physical layer is divided into two parts to the processing of data, and bit-level is handled and the symbol level processing, make a start and the bit-level processing procedure of receiving end respectively referring to Fig. 1 and Fig. 2.
In the bit level was handled, processing: the TB that makes a start (Transmit Block, transmission block) utilized the code block partitioning algorithm to be divided into several CB (Code Block, code block) after adding 24 CRC (Cyclic Redundancy Check, CRC) sign indicating number.When the CB number greater than 1 the time, each CB does follow-up processing after adding 24 CRC check sign indicating numbers again; If the bit number of TB is less, need not cut apart, just do not need to add again the CRC of CB.That is, when having a plurality of CB, TB has CRC check, CB that CRC check is also arranged.Therefore, receiving end, the analysis result of TB and each CB can be learnt through the CRC check result of CB level.
Based on above thinking, basic thought of the present invention is: in uplink coordinated process, and the sub-district cross-check result that cooperation is concentrated, whether the negotiation cooperation cell that distributes need send data to Serving cell.When needs send, cooperation cell can a transmitting section packet or entire packet give Serving cell, the same grade data of the information correction that the Serving cell utilization is received oneself, packet procedures is separated in completion.
Wherein, the concentrated sub-district of said cooperation comprises the cooperation cell of Serving cell and some participations cooperation.In uplink coordinated process, the user sends data, and the sub-district that said cooperation is concentrated all receives, and independently unpacks.
Said distribution is consulted to be meant: cooperation cell adopts distributed algorithm to make a strategic decision out needs to send the cooperation cell of data, and guarantees that in different cooperation cell result calculated be consistent.Particularly, be meant: whether each cooperation cell decision-making goes out this cooperation cell need send data to Serving cell, and, send if desired, then need send total data or partial data to Serving cell.
Said transmitting section packet is meant: when packet TB was big, TB was divided into a plurality of CB in cataloged procedure, and the result who consults that distributes only needs transmitting section CB for cooperation cell.
Said transmission entire packet is meant: packet TB hour, TB need not cut apart in the cataloged procedure, the result who consults that perhaps when TB is divided into a plurality of CB, distributes need send total data for cooperation cell.
Further, said transmitting section packet is meant transmitting section CB grade data bag.
Further, said transmission total data is meant the data of sending TB level or soft bit-level or IQ sample stage.
Particularly, the present invention provides a kind of uplink coordinated collection information interacting method, mainly adopts following technical scheme:
Step 1: the independent parsing after the data of cooperation UE received in the sub-district that cooperation is concentrated, and preserves TB data and check results thereof;
If when TB is divided into a plurality of CB in separating packet procedures, packet and the check results thereof that also will preserve each CB.
Step 2: mutual check results separately between the sub-district that cooperation is concentrated; If satisfy condition, Serving cell sends response message simultaneously and gives cooperation UE.
Said check results comprises the check results of the TB of this sub-district, when TB is divided into a plurality of CB in separating packet procedures, also comprises the check results of CB.
Serving cell:, send ACK (ACKnowledge, affirmative acknowledgement) and give all cooperation cell if the TB verification is correct; Send ACK simultaneously and give cooperation UE, need not carry out subsequent step, accomplish this receiving course;
Otherwise, send NAK (Non-ACKnowledge, negative response) and give all cooperation cell; When TB is divided into a plurality of CB, also need add the check results of CB.
Cooperation cell:, send ACK to the sub-district in all cooperation collection if the TB verification is correct;
Otherwise, send NAK to the sub-district in all cooperation collection; When TB is divided into a plurality of CB, also need add the check results of CB.
Step 3: the cooperation cell that said cooperation is concentrated is mutual according to the analysis result coordination data of the step 2 that receives.
Serving cell (it is wrong to separate the TB bag):
If receive that the TB of cooperation cell unpacks the result ACK is arranged, then send ACK and give UE, wait for that other cooperation cell transmission packets are to oneself.
Cooperation cell: if receive the ACK message of Serving cell, it is correct to show that Serving cell receives the TB bag, does not then need interaction data, and this receiving course is accomplished;
Otherwise if own XieTBBao is correct, and cooperation concentrates to have only and oneself separates rightly, and when the TB of Serving cell does not have subpackage, perhaps the TB of Serving cell has subpackage and all CB to separate to stagger the time, and directly transmission has been separated right TB and given Serving cell; When the TB of Serving cell has subpackage, and have CB separate to the time, send Serving cell and separate wrong CB and give Serving cell;
If own XieTBBao is correct, and cooperation concentrate to also have other sub-districts also to separate right, utilize decision algorithm which is judged and separate right sub-district and send correct information and give Serving cell; If judged result is oneself, then send TB or CB and give Serving cell, particularly, when the TB of Serving cell does not have subpackage, perhaps the TB of Serving cell has subpackage and all CB to separate to stagger the time, and directly transmission has been separated right TB and has been given Serving cell; When the TB of Serving cell has subpackage, and have CB separate to the time, send Serving cell and separate wrong CB and give Serving cell;
If oneself separate TB bag mistake, and cooperate and concentrate when having the sub-district to separate to TB, then need not send packet, receiving course has this time been accomplished in this sub-district;
If oneself separate TB bag mistake, and cooperate and concentrate when not having the sub-district to separate, when TB does not have subpackage, then send the TB that separates mistake and wrap to Serving cell to TB; When TB has subpackage, then separate wrong the unpack result of each CB in all cooperation cell and judge to Serving cell:
If certain CB unpacks correctly in this sub-district, and all unpack mistake in other cooperation cell, then this sub-district is sent this CB packet and is given Serving cell;
If certain CB unpacks correctly in this sub-district; And in other cooperation cell, also unpack correct; Then utilize decision algorithm which is judged and separate right sub-district and send correct CB packet,, then send this CB packet and give Serving cell if judged result is oneself to Serving cell;
If certain CB unpacks mistake in this sub-district, and other cooperation cell unpack correctly, and then this CB packet need not sent in this sub-district;
If certain CB unpacks mistake in this sub-district, and other cooperation cell unpack equal mistake, and then this sub-district is sent this CB packet and given Serving cell.
Step 4: Serving cell is received the packet that cooperation cell is sent, and merges and resolves.
Serving cell: (oneself separate TB bag wrong) handled the packet that cooperation cell is sent out: if what receive is correct TB bag, then directly replace with correct with oneself separating wrong TB bag; If what receive is soft bit-level or IQ sample stage data, after the same grade data that then will collect merges, do further parsing.
If what receive is CB bag, and it is right to be that cooperation cell is separated, and then oneself separates wrong with separating right CB replacement; If what receive is the CB bag, and be that cooperation cell is separated mistake, then adopt CB level merging method to merge a plurality of sub-districts and all separate this wrong CB result; Then, further separate TB with revised CB information.
Step 5: after the Serving cell merging unpacks, when CB level information merging parsing TB result is correct, give UE, then send ACK and give UE if send ACK; Otherwise, send NAK and give UE; Accomplish this and separate packet procedures.

Shown in accompanying drawing 5, comprise following base station in the present embodiment scene:
eNB0(cell01、cell02、cell03)；
eNB1(cell11、cell12、cell13)；
eNB2(cell21、cell22、cell23)；
eNB3(cell31、cell32、cell33)。
For being without loss of generality, this example is analyzed the UE00 among the cell02.If the Serving cell of UE00 is cell02, cooperation cell is concentrated has 3 sub-district: cell02, cell11, cell23, belongs to eNB0, eNB1, eNB2 base station respectively.X2 interface connects between the base station.
If the packet that UE00 sends is TB0, the bit level is divided into 3 CB when handling, and is respectively CB0, CB1, CB2.
Uplink coordinated process: UE00 sends data, and all cooperation cell receive, and after the independent respectively decoding, determines whether to merge according to the result.The concrete steps of this example are described below:
Step 1: all carry out independently unpacking after the data of UE are received in the sub-district that cooperation is concentrated, and preserve TB and unpack the result; If judge that in separating packet procedures TB is divided into a plurality of CB, then preserves the result that unpacks of each CB.
Suppose in this example, Serving cell and cooperation cell independently to unpack the result as shown in the table:
Independently decode and preserve decoded result in table 1 sub-district
Step 2: in the sub-district of cooperation collection mutual separately independently unpack the result; If satisfy condition, Serving cell sends response message simultaneously and gives UE.
Serving cell:, send ACK (ACKnowledge affirmative acknowledgement) and give all cooperation cell if TB unpacks correctly; Send ACK simultaneously and give UE, need not carry out subsequent step, accomplish this receiving course;
Otherwise, send NAK (Non-ACKnowledge negative response) and give all cooperation cell; When TB is divided into a plurality of CB, also need add the result that unpacks of CB.
Cooperation cell:, send ACK to the sub-district in all cooperation collection if TB unpacks correctly;
Otherwise, send NAK to the sub-district in all cooperation collection; When TB is divided into a plurality of CB, also need add the result that unpacks of CB.
Wherein, CB unpacks the result and can indicate with bitmap, and wherein to be that 0 the corresponding CB of expression resolves correct for the bit value, and bit value is 1 to represent parse error;
Perhaps, CB unpacks the result and also can add mistake CB the encoding list and indicate with separating wrong CB number, and for example, the CB number of mistake is 2, is respectively 0,2 by from small to large sequence number, and expression CB0 separates mistake with CB2, and remaining CB resolves correctly.
Need to prove that CB unpacks the result does not influence the realization of invention with any mode, adopt the mode of bitmap to indicate in the following table.
Mutual decoded result after independently decoding in table 2 sub-district
Step 3: the sub-district of cooperation collection is analyzed after receiving and unpacking the result, and interaction data as required.
Serving cell (it is wrong oneself to separate the TB bag): if receive that the TB of cooperation cell unpacks the result ACK is arranged, then send ACK and give UE, wait for that other cooperation cell transmission packets are to oneself.
Cooperation cell: if receive the ACK message of Serving cell, show that Serving cell XieTBBao is correct, then do not need interaction data, this receiving course is accomplished;
Otherwise if own XieTBBao is correct, and cooperation concentrates to have only and oneself separates rightly, and when the TB of Serving cell does not have subpackage, perhaps the TB of Serving cell has subpackage and all CB to separate to stagger the time, and directly transmission has been separated right TB and given Serving cell; When the TB of Serving cell has subpackage, and have CB separate to the time, send Serving cell and separate wrong CB and give Serving cell;
If own XieTBBao is correct, and cooperation concentrate to also have other sub-districts also to separate right, utilize decision algorithm which is judged and separate right sub-district and send correct information and give Serving cell; If judged result is oneself, then send TB or CB and give Serving cell, particularly, when the TB of Serving cell does not have subpackage, perhaps the TB of Serving cell has subpackage and all CB to separate to stagger the time, and directly transmission has been separated right TB and has been given Serving cell; When the TB of Serving cell has subpackage, and have CB separate to the time, send Serving cell and separate wrong CB and give Serving cell;
If oneself separate TB bag mistake, and cooperate and concentrate when having the sub-district to separate to TB, then need not send packet, receiving course has this time been accomplished in this sub-district;
If oneself separate TB bag mistake, and cooperate and concentrate when not having the sub-district to separate, when TB does not have subpackage, then send soft bit-level data or IQ sample stage data to TB; When TB has subpackage, then separate wrong the unpack result of each CB in all cooperation cell and judge to Serving cell:
If certain CB unpacks correctly in this sub-district, and all unpack mistake in other cooperation cell, then this sub-district is sent this CB packet and is given Serving cell;
If certain CB unpacks correctly in this sub-district; And in other cooperation cell, also unpack correct; Then utilize decision algorithm which is judged and separate right sub-district and send correct CB packet,, then send the correct Solution inclusion of this CB and really give Serving cell if judged result is oneself to Serving cell;
If certain CB unpacks mistake in this sub-district, and other cooperation cell unpack correctly, and then this CB packet need not sent in this sub-district;
If certain CB unpacks mistake in this sub-district, and other cooperation cell unpack equal mistake, and then this sub-district packet of sending this CB is given Serving cell.
Wherein, when sending TB bag or CB and wrap to Serving cell, needing this bag of mark is oneself to separate right or separate wrong.
Wherein, decision algorithm is decided by concrete realization, only need guarantee independently to calculate in each sub-district, but finally have only a definite result, for example, gets the maximum or minimum of cell number in the set, or the like, the present invention does not do concrete restriction.
Interaction data behind the mutual decoded result in table 3 sub-district
Step 4: Serving cell is received the packet that cooperation cell is sent, and merges and resolves.
Serving cell (it is wrong oneself to separate the TB bag) is handled the packet that cooperation cell is sent out:
If what receive is to separate right TB bag, then directly replace with correct with oneself separating wrong TB bag; If what receive is soft bit-level or IQ sample stage data, after the same grade data that then will collect merges, do further parsing;
If what receive is CB bag, and it is right to be that cooperation cell is separated, and then oneself separates wrong with separating right CB replacement;
If what receive is the CB bag, and be that cooperation cell is separated mistake, then adopt CB level merging method to merge a plurality of sub-districts and all separate this wrong CB result;
Then, further separate TB with revised CB information.
Step 5: after the Serving cell merging unpacks, when CB level information merging parsing TB result is correct, give UE, then send ACK and give UE if send ACK; Otherwise, send NAK and give UE; Accomplish this and separate packet procedures.
Table 4 Serving cell sends amalgamation result to UE after merging parsing as required
Applying examples two: the application scenarios one of less TB
The present invention is suitable for the scene of less TB too; Less TB is meant that TB is not divided into a plurality of CB when doing the bit level and handle, and that all processing procedures can be with embodiment 1 is consistent; Because there is not the processing of CB, therefore can deteriorates to typical TB and separate the packet procedures realization.
The concrete steps of this example are described below:
Step 1: all carry out independently unpacking after the data of UE are received in the sub-district that cooperation is concentrated, and preserve TB and unpack the result.
Step 2: in the sub-district of cooperation collection mutual separately independently unpack the result; If satisfy condition, Serving cell sends response message simultaneously and gives UE.
Serving cell:, send ACK (ACKnowledge affirmative acknowledgement) and give all cooperation cell if TB unpacks correctly; Send ACK simultaneously and give UE, need not carry out subsequent step, accomplish this receiving course;
Otherwise, send NAK (Non-ACKnowledge negative response) and give all cooperation cell.
Cooperation cell:, send ACK to the sub-district in all cooperation collection if TB unpacks correctly;
Otherwise, send NAK to the sub-district in all cooperation collection.
Step 3: the sub-district of cooperation collection is analyzed after receiving and unpacking the result, and interaction data as required.
Serving cell (it is wrong oneself to separate the TB bag): if receive that the TB of cooperation cell unpacks the result ACK is arranged, then send ACK and give UE, need not carry out subsequent step, accomplish this receiving course;
Otherwise wait for that other cooperation cell transmission packets are to oneself.
Cooperation cell: if receive the ACK message of Serving cell, show that Serving cell XieTBBao is correct, then do not need interaction data, this receiving course is accomplished;
Otherwise, if own XieTBBao is correct, and cooperation concentrate have only oneself separate to the time, directly transmission has been separated right TB and has been given Serving cell;
If own XieTBBao is correct, and cooperation concentrate to also have other sub-districts also to separate right, utilize decision algorithm which is judged and separate right sub-district and send correct information and give Serving cell; If judged result is oneself, directly transmission has been separated right TB and has been given Serving cell;
If oneself separate TB bag mistake, and cooperate and concentrate when having the sub-district to separate to TB, then need not send packet, receiving course has this time been accomplished in this sub-district;
If oneself separate TB bag mistake, and cooperate and concentrate when not having the sub-district to separate, then send soft bit information or IQ sampled data and give Serving cell to TB.
Step 4: Serving cell is received the packet that cooperation cell is sent, and merges and resolves.
Serving cell (oneself separate TB bag wrong) is handled the packet that cooperation cell is sent out: if what receive is to separate right TB bag, then directly replace with correct with oneself separating wrong TB bag; If what receive is soft bit information or IQ sampled data, the information of then doing appropriate level merges, and finally accomplishes the parsing of TB level information.
Step 5: after the Serving cell merging unpacks, when parsing TB result is correct, give UE, then send ACK and give UE if send ACK; Otherwise, send NAK and give UE; Accomplish this and separate packet procedures.
In sum; The present invention proposes a kind of optimization method during to up CoMP cooperation collection interactive information; With respect to transmission TB level, CB level, soft bit level or IQ data in the Combined Treatment typical method; This method only needs hop CB, and is the part that Serving cell needs most, and has reduced the pressure to X2 interface/eat dishes without rice or wine; Merge with respect to mutual soft bit information and IQ data, CB is the information of relative higher level, can alleviate the processing burden of Serving cell; This method is better compatible, and the scene advantage of big TB is outstanding, and the scene of little TB is not introduced overhead yet.
